CIRCUIT-CONTROLLING DEVICE.

Specification of Letters Patent.

Patented A r. 18, 1916.

To all whom it may concern:

Be it known that I, JOHN T. AUSTIN, a. citizen of the United States, residing at Hartford, in the county of Hartford and State of Connecticut, have invented certa n new and useful Improvements in Circuit- Controlling Devices, of which the following is a specification.

This invention relates to circuit-controlling devices. A circuit controlling device involving the invention is susceptible of general use, although it is of particular utility when employed in conjunction with or as part of an organ stop mechanism. In this particular employment the device is employed to cause the consecutive or successive action of stops in order to obtain crescendo effects or the simultaneous action of the stops.

In the following description I will set forth in detail that one of the several convenient forms of embodiment of the invention, which I have selected for illustration in the drawings accompanying and forming part of the present specification, this showing being provided to enable those skilled in the art to practise the invention.

I do not restrict myself to such disclosure; I may depart therefrom in several respects within the scope of the invention defined by the claims following said description.

Referring to said drawings: Figure 1 is a perspective view of a circuit-controlling device involving my invention and associated with organ stop mechanism, a portion being broken away and parts only of two pedals being shown. Fig. 2 is a like view seen from the opposite side. Fig. 3 is a detail view in section hereinafter more particularly described.

Like characters refer to like parts throughout the several views.

The organization shown comprises several stop governing devices which as shown consist of magnets as 2, the number of magnets corresponding to the number of stops. The magnets are represented as being of horseshoe type, although this is merely a matter of detail.

The organ-pipes are denoted by 3 and cooperative with each is a stop slider 4 both of familiar construction. Each slider 4 is connected by a link as 5 with one branch of an angle lever 6 pivoted at its elbow, the other branch constituting an armature for the cooperating magnet. In Fig. 2 the magnets 2 are supposed to be deenergized, the stop sliders 4 being closed and maintained in such relation .by springs as 7 connected with the respective angle levers 6 or equivalent parts. On the energization of a magnet the armature branch of the cooperating lever 6 is attracted to draw the stop slider 4 as shown in Fig. 1. As will hereinafter appear I provide means by which the magnets 2 can be energized, one after the other, or can be energized simultaneously. In the first case as will be understood I obtain a crescendo effect and in the other full organ. Certain of the operative parts are sustained by the base member 8 to the back or inner side of which is fastened the wedge member 9, the upper portion of which slopes upwardly from the fore ground in Fig. l or downwardlyfrom the foreground in Fig. 2, the contact member or conductor 10 being laid upon and suitably fastened to theupper inclined edge of the wedge member 9. Cooperative with the contact member 10 are circuit controlling members or elements 11 which may consist of bared wires of proper gage, the contact 10 consisting also of bared wire. In the present instance the circuit-controlling members 1.1 are gravitative; that is to say they tend to normally move toward circuit closing positions by gravity assisted by the resilience of said members 11 as will hereinafter appear. These circuit-controlling members as shown are clamped against the upper edge of the board 12 fitted rigidly in a channel in the base member 8 by a strip as 13. As will be clear the circuit-controlling members 11 are free between the clamping element 13 and the wedge member 11, so that when permitted to do so as will hereinafter appear, they can descend upon the inclined contact element 10. Each of the circuit-controlling members 11 is connected to a magnet 2 and to a suitable source of electrical energy by a wire or other suitable conductor as 14. The source of electrical energy shown is the battery 15 to one pole of which the several conductors or wires 14 are con nected, the wire 16 leading from the opposite pole of the battery and being connected with one end of the contact or conductor 10. It therefore, follows that when a circuit controlling member 11 engages the conductor 10 the magnet in the branch circuit with said part 11 is energized to effect the action of a cooperating stop through thecircuit con nections described.

To normally uphold the circuit controlling elements 11 any desirable means maybe provided, for instance the swinging member 17 located in the channel 18 in the upper side of the board 8 and hinged or otherwise connected to said board 8 at one side of the channel 18. Then this swinging member is in its initial position as shown in Fig. 2, it engages the circuit controlling elements or wires 11 to uphold the same and thereby prevent their engaging the conductor or contact element 10 as shown in Fig. 2. To advance or swing down the member 7 any desirable'means may be provided, for example the pedal 19 to which the link 20 is connected, the link bein also connected with the swinging member 1 on one end between the center of motion and free edge thereof. On the operation of the pedal 19 the part 17 can be swung down from the position shown in Fig. 2 to that illustrated in Fig. 1, so that the circuit controllers 11 can successively engage the conductor 10 to thereby obtain in the manner already described, the

consecutive action of the stops. To return the part 17 to the initial position thereof springs as 21 connected therewith and also with the base member 8 may be provided.

There may be cases Where it is desired to eifect the action of an individual stop or one or more of them independently of the companion stops, and-for this purpose, the following means may be provided. Each wire 16 may have running from it the branch wire 22 extending from it and connected with the fixed contact 23 cooperative with the spring contact 24:. From each contact 24 the wire- 25 extends and is connected to a wire 14. The draw knobs are designated by 26, and their shanks are provided with pins 27 cooperative with the spring contacts 2 1. When a knob 26 is pulled the pin 27 will move the spring contact 24 against the fixed contact 23 associated therewith. thereby effecting the energization of the magnet 2 in circuit with the particular contact 24:, thus securing the operation of the coacting stop.

There may be cases where it is desired to throw on all the stops or all those of a group simultaneously, and for this purpose the means new to be described is quite satisfactory. Mounted on the under side of the base 8 is the conductor 28 engaged electrically by the bent portions 29 of the fingers 30, said fingers being held in place near their butts by the strip 81 fastened suitably to the under side of the base member 8, the fingers 30 extending upwardly through the base member and their free portions being disposed between and normally out of contact with the circuit controlling members 11. Mounted on the upper side of the base 8 is the plate or bar 32, having notches or slots 33 to receive the free portions of the fingers 30, the plate 32 being confined in position by staples as 35 straddling the same. Connected to one-end of the plate or bar 32 is one arm of the angle lever 34: pivoted at its elbow to the extension of the strip 31, the link 36 being connected with the other branch of said angle lever 34. The link is also connected with the pedal 37 which with the companion pedal 19 is supported for oscillation by the shaft 38. On the operation of the pedal 37 the plate or bar 32 can be advanced through the agency of the described parts to move the free portions of the fingers 30 against the circuit controllers 11 and thereby effect the energization of all the magnets 2 and the consequent action of all the stops. The circuit controllers 11 are disposed respectively between parallel posts or uprights 40 rising from the base board 8 and connected at their tops by the bar 11, said posts or uprights preventing undue lateral movement of said circuit controllers.

' What I claim is:

1. The combination of an inclined conductor, a plurality of circuit controllers nor- -mally movable toward said conductor, and

means for holding the circuit controllers normally out of contact with said conductor and movable to permit said circuit controllers to successively engage said conductor.

2. The combination of a wedge member having a conductor upon its inclined face, a plurality of circuit controllers, and means for causing said circuit controllers to successively engage said conductor.

3. The combination of an inclined conductor, a plurality of circuit controllers normally movable toward said conductor, a member for holding the circuit controllers in a line at an angle to said conductor and normally out of engagement with said conductor, said member being movable to permit said circuit controllers to successively engage said conductor.

4. The combination of a conductor, a plurality of circuit controllers normallymovable toward said conductor, a member, means acting against said member to cause the latter to hold the circuit controllers in a line at an angle to said conductor and normally out of contact with the conductor, and means for operating said member to permit the controllers to successively engage said conductor.

5'. The combination of an inclined conductor, a plurality of circuit controllers, means for causing said circuit controllers to .succesively engage said conductor, conducting fingers cooperating'w'ith the circuit controllers and normally out of contact there mally movable toward said conductor, and a member for holding the circuit controllers in a plane at an angle to said conductors and normally out of engagement with said conductor, said member being movable to permit said circuit controllers to successively engage said conductor.

In testimony whereof I afiix my signature in presence of two witnesses.
